2 цел 5/11 х-1 цел 2/9+3 цел 6/11 х

1. x * (1-7/9-1/12) = 5/36*1/4

x * (36/36-28/36-3/36) = (5*1) / (36*4)

x * ((36-28-3) / 36) = 5/144

x * (5/36) = 5/144

x=5/144:5/36

x+5/144*36/5

x = (5*36) / (144*5) = 180/720=1/4

2. 2 целое5/11x+3 целое6/11x=1 цел2/9

x * ((2+3) + (5/11+6/11)) = 11/9

x * (5+11/11) = 11/9

6x=11/9

x=11/9:6

x = (11*1) / (9*6) = 11/54
